We present a case of an antenatally diagnosed congenital aneurysm of the left ventricle in which fetal cardiac contractility was evaluated by measuring the fetal isovolumetric contraction time (ICT). The workup of the fetus at 26 weeks' gestation led to the identification of a left ventricle aneurysm. Initially, the value of ICT of the left ventricle indicated adequate cardiac function. However, the fetal ICT was gradually prolonged, suspecting deteriorated cardiac contractility. Following an uncomplicated term delivery, a postnatal echocardiogram showed normal cardiac function. It is considered that because of the hypokinesis of the wall of the left ventricular aneurysm, the ICT did not fully predict cardiac function in this setting.
我们报告一例产前诊断为左心室先天性动脉瘤的病例，其中通过测量胎儿等容收缩时间（ICT）评估胎儿心脏收缩功能。对妊娠26周的胎儿进行检查时发现了左心室动脉瘤。最初，左心室的ICT值表明心脏功能正常。然而，胎儿ICT逐渐延长，怀疑心脏收缩功能恶化。在足月顺产且无并发症后，产后超声心动图显示心脏功能正常。据认为，由于左心室动脉瘤壁运动减弱，在这种情况下ICT未能充分预测心脏功能。
